Abstract
Wetlands are natural reservoirs that are formed in sunken and enclosed areas and are fed by surface or underground streams or both. The subsidence of wetlands is generally caused by geological and geomorphological factors, which are based on the action of natural factors. Agh Gol pond is located in the deepest part of the Shera river basin (Qarachai) on the political border of the two provinces of Mazari and Hamedan. The purpose of the current research is to study and investigate the development of geology and geomorphology and fluctuations and surface changes of Agh Gol wetland in the Quaternary period based on geological evidence, the spread and thickness of alluvial sediments. For this purpose, library sources such as books, articles, Reports, 1:25000 topographic map of the mapping organization, 1:100000 geological and tectonic map, Aster sensor images in Google Earth Engine software environment and field observations were used. The results indicate that at the beginning of the Quaternary, the area of the wetland was in the form of a large depression and the alluvial sediments resulting from erosion were transported to it by surface currents. It has become a seasonal wetland and the level of the wetland is limited to the sunken middle parts. Satellite images showed that in terms of morphology, this wetland does not have diverse and complex forms.
